Answer:
x=7
Step-by-step explanation:
3^(x−5) = 9
Rewrite 9 and 3^2
3^(x−5) = 3^2
Since the bases are the same, the exponents have to be the same
x-5 = 2
Add 5 to each side
x-5+5 =2+5
x = 7
Explanation:
Use the Pythagorean identity, cancel common factors, and divide numerator and denominator by cos(x). Equivalently, multiply numerator and denominator by sec(x).

If you're finding the mean for row 1 and row 5, remember that the mean is the same as finding an average. You would add all the numbers together then divide by how many you added.
Let me show you:
Row 1: 6, 5, 2, 8, 6
Row 5: 2, 3, 2, 2, 4
Add all the numbers from row 1 and 5 together.
You will get a value of 40.
Now divide number by how many numbers you added together, in this case we would divide 40 by 10, because we added together 10 numbers.
40 / 10 = 4
Thus, your mean/average would equal 4.
I hope this helps!
There are lots of them I know but I will only give you a few of them.
14/30 56/120
21/45 63/135
28/60 70/150
35/75 77/165
42/90 84/180
49/105 91/195
In two hours, they have produced 600 jars. so they are working at 300 jars per hour. 1800-600=1200 and 1200 divided by 300 is 4 so they will finish work at 10:30+4:00, 14:30/2:30pm
